Package as module, add console entry point

Moved python files into `stormkafkamon` dir, and created a `setup.py` that fetched all the dependencies and also creates an executable called `skmon`.

I've left some fields in `setup.py` empty, e.g. `author` and `author_email`, please let me know what you want there, or you can edit them later.

This should make it much easier for folks to begin using stormkafkamon.
